GAS-BURNER.

' Specification of Letters Patent.

Application filed November 8,1909, Serial No. 526,683. Renewed July 5, 1912. Serial No. 707.906.

To all whom it may concern? Be it known that I, EDWIN G. Van ZANDT, acitizen of the United States,'and resident of the city of Sta-Louis and State, f Missouri, have invented certain new an' useful Improvements in Gas-Burners, of w-h'ich the following is aspecification.

This invention relates to gas-burners and more particularly to such as shown in the United States Letters Patent No. 838,596,

. granted to me December-18,1906, and Let tei's PatentNo. 876,507, granted tome J an.-

uary.14, 1908 and this invention relates more particularly to an improvedburner, and its object is to rovide a-vertically arranged burner in wh ch most of the products {10f combustion of-an initial burn-er are consmiled, and in which the second burner fea- 'ture is utilized.

one embodiment of my invention, and Figlfl2 is a vertical transverse of the container 7 by struts or members 12,

videdwith a plurality ofopenings 10 ata short distance from the top of the container and equally spaced from each other, the Openings 10 acting to bring about a horizontal draft, Superimposed on the open end of the cylindrically-shaped container 7 1s a top-plate 11 spaced apart from the top so arranged as to provide an opening between the topofthe container 7 and the bot-- fin n of the top-plate 11. The top-plate 11 isfurther provided with a plurality of openings 13 spiced an equal distance apart in the embo'di ent shown in: the drawing, of V- shape, though the walls thereof may also be parallel, the object of which openings is to,

permit the outflow of combustible gases re- ;sultin from the initial burning andv now unignlted from the interior of the container ,In-"the accompanying drawing, Figure 1 s a pIan-vie w o and cause their ignition at the exterior or,

top of top-plate 11. The openings 13 are.

'. Patented Nov. 26, 1912 i preferably V-shaped in the vertical section v so as to aid in the outflow of gas and also'in the ignition of the same. The top-plate 11 is further provided with projections 11 pref} erably-spaced equally distant apart, the object of which is to provide supportsfor any culinary {vessels which might be placed onthe burner. The to -plate 11 in the embodiment shown in t e drawings extends a certain distance beyond the container 7, and

the object of'this is to cause a deflection and spreading of the flame emanating from the openings '10 and also to permit a further supply of air passing from the interior of the container 7 and between the top of the container and the bottom of the top-plate, to come in contact with the flames einanat-" ing from the openings 10 of. the container 7. The stream of hot products of combustion will have their combustibleportions ignited and form an additional flame.

The invention, therefore, consists in the arrangement of an upright cylindrical cont tamer surroundlng an 1n1t1al burner and having a top-plate arranged in close prox; I

imity to the shell to prevent the flames fro'iii the initial burner from extending over and beyond the shell and cause the products of combustion to burn at the immediate exterior -of the shell between the shell and 5 plate, the initial burner having its flame near the lower part of the shell and the shell having lateral perforations therein. And also in providing a top-plate with-openings which are restricted to prevent/Mic flame from the initial burnerfrom passing there through, and also to burn at the immediatev exterior ofthe plate the products of combustion passing through the openings. And

further in providing the plate with an extension so as to protect the shell. And further in providing lugs between the top-plate Y of the shell and the shell.

The flames emanating from the openings at the top of the shell or container and burning ofl' of'and around the edges of the vents in the top of the shell or container are thin and almost transparent and of ery little heat inasmuch as the hand can be placed in the flame for some time without injury.-

I have shown one embodiment of my invention, but I do not wislrto limit myself to Y the details of the same, since changes may be departing from the opening, and a top-plate provided with lindrical shell and openings, the top-plate being spaced some distance above'the lprovided with. a

portionshell.

In a gas-burner, the combination of a shell having an open upper end and'a plurality of perforations near the upper edge thereof, a top-plate spaced above said end and edge and extending beyond said edge, and an initial burner adapted to discharge its products of combustion into said shell.
